Acro with no coralites?

[mic209]

Been struggling with identifying this acro I've had since December. Colors coming through are just like a sunset Milli, growth pattern just like a Milli, polyps look just like a Milli, but it's skeleton is smooth just like a montipora digita. Any ideas? First pic is today after a snail grazed by it and it's polyps retracted, second pic was in December when I first got it.

It has axial coralites, it's deffinitly a acropora, I'm 95% sold its a millipora.
